CHAPLET.

Application led April 22,

To all whom t may concern,

Be it known that I, HENRY BELLON, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Chaplets, of which the following is a specification.

This invention relates to chaplets used extensively in the art of casting molten metal for the purpose of supporting cores within the mold prior to and during the pouring of the metal.

The object of the present invention is to provide a simple and inexpensive chaplet,

and one which may Ibe readily made by a machine capable o-f punching and forming the same in a single operation. A further object of the invention is to provide a chaplet especially designed to permit the free flow of molten metal thru the same in all directions, with a view of avoiding the formation of air and gas pockets in the metal, and a resulting defect in the casting. To accomplish this end, an open structure is desirable, coupled with a reduction in the area of edges and surfaces presented to the flowing metal.

A preferable form of chaplet is illustrated in the accompanying drawing, the same being shown in perspective.

The method contemplates for the making of chaplets such as is herein illustrated and described, is one employing machinery; that is, a punch press whereby each article is punched from a blank strip of metal fed to the machine, and bent into final form. Each blank, as it is cut from the strip, 1s punched to form two rectangular openings 2 adjacent the ends of the blank, these openings being spaced apart or separated by a central body portion 1 located centrally of the blank. The punching of the rectangular openings removes portions of the metal of like shape, there remaining along the sides of the openings 2, relatively narrow portions 3-3 extending longitudinally of the blank,

and narrow transverse portions 4-4 joining the ends of the longitudinal side portions 3-3 together.

Each blank thus punched in the manner 1921. Serial No. 463,474.

described, is bent by means of suitably formed dies into the shape illustrated; that is, with the end portions bent substantially at right angles to the central body portion, altho in the final form the body portion includes portions of the longitudinal portions in that the line of transverse bending is spaced outwardly from the central body portion l, and therefore the longitudinal portions 3 3 only, are actually bent. Thus 60 the body portion 1, and a part of longituv dinal portions 3-3, forno the base A of the chaplet, and the transversely bent end portions provide legs B--B, these legs being again bent at right angles, and inwardly at points adjacent the ends to form feet C-C,- the latter including the ends of the longitudinal portions 3-3 of the fblank and the transverse portions 4 4.

Carried on simultaneously with the bending operation is a forming or shaping operation that gives the chaplet its iinal form, this depending on the size and use for which the particular chaplet is designed. For example, the base A may be slightly curved;

that is, concaved on its under side, the legs B-B 4sligh ly tapered or convergent, and the feet C-C set parallel to the base A. However, the ultimate shaping of the chaplets is a matter of choice, and would ordinarily be varied according to the particular molcling operation for which they are to be use A chaplet made in the manner described is a comparatively simple structure, and thereufore lends itself especially to quantity production methods of manufacture, and at the same time has all of the characteristics of a desirable chaplet; namely, the strength to properly support a core within the mold, and yet of suiiicient open structure to permit the free and unobstructed How of metal thru them in all directions.

Having described a preferable form of chap-let structure, and the advantages thereof, I claim as my invention:

1. A chaplet consisting of a blank, shaped to form a base portion, upstanding legs at opposite ends of the base, and feet extending inwardly and parallel to said base, said leg portions having their central portions ing portions of said openings, pairs of upremoved to form relatively large openings standing legs spaced apart, and feet connecttherebetween. ing the ends of said pairs of legs and bent 10 2. A chaplet consisting of a rectangular substantially parallel With said base portion. 5 blank having rectangular openings on either ln Witness whereof, I hereunto subscribe side of the central portion thereof, and bent my name this 19th day of April, A. D., 1921. transversely to form a base portion, includ- HENRY BELLON.
